Hedge, Double-up, Sell Back
In Simple Trader, the platform allows the trader to advance his trading options by offering the following features:

Hedge
Clicking the "Hedge" button will duplicate the trader's position with the exact terms (same Instrument, expiry, investment amount, payout) - but will open the trade in the opposite direction with an updated strike price.
So for example, if you hedge a trade of "High, EUR/USD, 60sec, $25, 81%", by clicking the "Hedge" button an immediate position will be opened - "Low, EUR/USD, 60sec, $25, 81%" with new strike price.
Double Up
Clicking the "Double Up" button will duplicate the trader's position with the exact terms (same direction, Instrument, expiry, investment amount, payout) - with an updated strike price.
So for example, if you hedge a trade of "High, EUR/USD, 60sec, $25, 81%", by clicking the "Double Up" button an immediate position will be opened - "High, EUR/USD, 60sec, $25, 81%" with new strike price.
Sell Back
The Sell Back feature allows you to close your trade and sell your option back to the system during the open trade time prior to the expiry time. You can use it to lock profit when your position is in-the-money and you feel that you may be out-of-the-money at the end of the chosen expiry time. You can use it to stop loss if your position is out-of-the-money and you feel that the asset will not change direction.
* Sell back is not available during the last 30 seconds prior to expiry.
* Return on sellback is dynamic and it is calculated based on volatility and distance to expiry
